Description

Technical Field

[0001] This invention relates to the field of soup pot technology, and specifically to a soup pot with an instant soup base display effect. Background Technology

[0002] In large-scale catering and hotel businesses, soup-based fast food chains, group catering companies, and soup shops, businesses that want to make bone broth on-site face problems such as high costs, time and labor, and inconvenience. In addition, if the broth is too thick and the raw materials such as the ingredients are not visible, consumers will not be willing to pay more for the meal if they cannot see the bone broth made with real ingredients, nor will they be willing to promote the restaurant on their own initiative. As a result, the business model of making high-quality bone broth on-site cannot be effectively promoted.

[0003] Therefore, designing a soup pot with an instant soup base display, allowing consumers to see the bone broth being simmered on-site and to see the high-quality ingredients inside, would make consumers more willing to pay more for the meal and spontaneously promote the restaurant, thus effectively solving the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a soup pot with an instant soup base display effect to solve the problems described in the background art.

[0005] The technical solution of this invention is implemented as follows:

[0006] A soup pot with an instant soup base display effect includes a base and an inner barrel with an upper opening located above the base. An observation window is provided on the side wall of the inner barrel, and a glass plate is sealed within the observation window. A grate is also provided inside the inner barrel. The grate includes a filter plate for filtering liquid and an annular side plate surrounding the outer edge of the upper surface of the filter plate. An upper rotating shaft is screwed through the center of the filter plate. The outer edge of the grate is slidably connected to the inner side wall of the inner barrel without rotation. The bottom of the inner barrel and the top of the base are connected by a rotating connector. The rotating connector includes an upper rotating component sealed in the bottom wall of the inner barrel and a lower rotating component located on the top of the base. A drive mechanism for driving the lower rotating component to rotate is also provided inside the base. The upper rotating component is detachably inserted into the top of the lower rotating component, and the upper and lower rotating components drive each other. The bottom of the upper rotating shaft drives the upper rotating component. A soup lid is also provided on the top of the inner barrel.

[0007] When using the above solution, by setting up an observation window and glass plate, diners can see the contents of the inner pot through the broth. The ingredients are placed in a grate, and the inner pot is filled with broth. The drive mechanism is activated, which in turn drives a rotating connector to rotate. This connector, in turn, drives an upper shaft. Because the grate is connected to the side wall of the inner pot without rotating, it slides up or down along the upper shaft, moving the ingredients within the grate into the observation window for diners to observe. Furthermore, the drive mechanism can be manipulated to keep the grate close to the broth surface within the observation window, ensuring the ingredients are always submerged in the broth while allowing diners to easily see them.

[0008] A further technical solution is that the upper rotating component includes an upper sealing plate. A limiting post is formed by an upward protrusion at the center of the upper end face of the upper sealing plate. An embedding groove leading to the interior of the limiting post is formed at the bottom of the upper sealing plate. A circular hole connecting the top of the limiting post is formed at the top of the embedding groove. The upper end face of the upper sealing plate also protrudes upward to form a first annular wall surrounding the limiting post. The outer wall of the first annular wall is sealed within the bottom wall of the inner tub. At least one first soup outlet hole is formed on the upper sealing plate between the limiting post and the first annular wall. An unsealed connecting rod is provided in the first soup outlet hole. A sliding hole is formed in the connecting rod. A sliding sleeve with an inner diameter larger than the sliding hole is fixedly installed at the bottom of the connecting rod directly below the sliding hole. A sliding rod slides through the sliding hole. A spring is sleeved on the sliding rod in the sliding sleeve. A top block is fixedly installed at the bottom of the sliding rod and slidably connected to the sliding sleeve. The top of the spring abuts against the bottom of the connecting rod, and the bottom of the spring abuts against the top of the top block. The top of the sliding rod is provided with a blocking block for sealing the first soup outlet from top to bottom. The lower end face of the upper sealing plate also protrudes downward to form four second ring walls surrounding the limiting post. The four second ring walls are concentrically arranged from the inside to the outside. The two second ring walls near the inside and the two second ring walls near the outside are respectively clamped in pairs to form annular upper limit grooves. The two upper limit grooves are also provided with upper sealing rings. The upper rotating part also includes a connecting plate. The upper upper surface of the connecting plate also protrudes upward to form an upper fixed bushing for inserting into the embedding groove. The upper upper surface of the connecting plate also protrudes upward to form two third ring walls for inserting into the two upper limit grooves. The connecting plate is screwed to the bottom of the upper sealing plate. The connecting plate between the two third ring walls is also provided with a second soup outlet. The bottom of the connecting plate protrudes downward to form two fourth ring walls surrounding the upper fixed bushing.

[0009] The lower rotating component includes a lower sealing plate, which is detachably installed on the top of the base. A lower fixed bushing is fixedly inserted at the center of the lower sealing plate. The upper end face of the lower sealing plate also protrudes upward to form four fifth ring walls surrounding the lower fixed bushing. The four fifth ring walls are concentrically arranged from the inside to the outside. The two fifth ring walls near the inside and the two fifth ring walls near the outside are respectively clamped to form an annular lower limiting groove. A lower sealing ring is also provided in each of the two lower limiting grooves. The two fourth ring walls are respectively inserted into the two lower limiting grooves. The sliding sleeve extends through the second soup outlet hole to the top of the lower sealing plate. The bottom of the top block abuts against the upper end face of the lower sealing plate. A third soup outlet hole is also opened in the lower sealing plate between the two middle fifth ring walls. A water guide chamber is also provided at the bottom of the lower sealing plate directly below the third soup outlet hole. A water outlet pipe is also connected to the bottom of the water guide chamber. A soup outlet control component and a soup outlet pipe are connected in sequence at the end of the water outlet pipe. The end of the soup outlet pipe extends out of the base.

[0010] A main gear is rotatably mounted in the lower fixed bushing. The drive mechanism drives the main gear to rotate in the lower fixed bushing. A secondary gear is also rotatably and slidably mounted in the lower fixed bushing. The secondary gear is located above the main gear and meshes with it. A coupling assembly is also rotatably and sealed in the upper fixed bushing. The upper end of the coupling assembly has a round hole that drives the upper rotating shaft. The lower end of the coupling assembly is connected to the secondary gear.

[0011] When using the above solution, first, the coupling assembly is rotatably and sealed in the upper fixed bushing, while the upper end of the coupling assembly passes through the round hole. Then, the first ring wall of the upper rotating component is installed in the bottom wall of the inner bucket with a through hole at the bottom, so that the outer side of the first ring wall is sealed to the through hole at the bottom of the soup bucket. The upper end face of the upper sealing plate abuts against the outer bottom of the soup bucket, thereby forming a limiting and fixing seal. Then, the lower rotating component is installed on the top of the base by installing the lower sealing plate on the top of the base.

[0012] When the soup pot is not placed on the base, the spring extends, pushing the top block downwards. The top block moves the sliding rod downwards, which in turn moves the block downwards, blocking the first soup outlet and preventing soup from leaking out. When the soup pot is placed on the base, the bottom of the top block is held in place by the lower sealing plate. The top block pushes upwards, moving the sliding rod upwards, which in turn moves the block upwards, disengaging it from the first soup outlet. Simultaneously, the fourth ring wall inserts into the lower limit groove, deforming and blocking the lower limit groove, sealing the connection between the upper and lower rotating parts. At this point, the soup flows downwards through the first soup outlet to the bottom of the upper sealing plate, then through the second soup outlet to the bottom of the connecting plate, entering the space between the two lower limit grooves of the upper sealing plate. Finally, it flows through the third soup outlet into the water guide chamber, and then out through the water outlet pipe at the bottom of the water guide chamber, supplying soup to the relevant components in the base, thus achieving an automatic soup dispensing function.

[0013] At the same time, when the upper rotating part and the lower rotating part are connected to each other, the secondary gear at the bottom of the coupling assembly is inserted into the lower fixed bushing and meshes with the main gear in the lower fixed bushing. This activates the drive mechanism at the bottom of the lower rotating part, causing the main gear to drive the secondary gear to rotate. The secondary gear then drives the coupling assembly to rotate. The upper end of the coupling assembly extends into the soup pot through the round hole, driving the upper rotating shaft to rotate.

[0014] A further technical solution is that the coupling assembly includes a cylindrical lower rotating shaft, the bottom of which protrudes radially outward to form a limiting ring, and the bottom of which protrudes axially downward to form a non-circular shaft. The top of the secondary gear is fitted onto the non-circular shaft. The top of the side wall of the lower rotating shaft is also provided with a lower external thread. A double-headed bushing is rotatably fitted on the lower rotating shaft. The bottom of the side wall of the double-headed bushing protrudes radially outward to form a stepped portion, the bottom of which abuts against the top of the limiting ring. A sealing ring is also rotatably fitted on the lower rotating shaft, the bottom of which abuts against the top of the double-headed bushing. The top of the lower rotating shaft also protrudes axially upward to form a connecting shaft, which extends upward through a circular hole. The lower external thread is located above the circular hole. The lower rotating shaft is also screwed with a nut through the lower external thread. The upper fixed bushing has concentric frustum holes, a first circular hole, a second circular hole, and a third circular hole from bottom to top. The bottom diameter of the frustum hole is larger than the diameter of the first circular hole, and the top diameter of the frustum hole is equal to the diameter of the first circular hole. The diameters of the first and third circular holes are both larger than the diameter of the second circular hole. The upper part of the double-headed bushing slides and rotates into the second circular hole, and the stepped part of the double-headed bushing slides and rotates into the first circular hole. The sealing ring slides into the third circular hole. The secondary gear is located directly below the frustum hole. The connecting shaft is driven by the bottom of the upper rotating shaft.

[0015] When using the above method, first insert the double-ended bushing into the upper fixed bushing from the bottom of the connecting plate. Then, insert the lower rotating shaft into the double-ended bushing from the bottom until the limiting ring abuts against the double-ended bushing. Next, slip the sealing ring onto the lower rotating shaft from the top until the sealing ring is inserted into the third circular hole from the top of the upper fixed bushing. Then, insert the upper fixed bushing into the embedding groove in the limiting post. Then, screw the connecting plate onto the bottom of the upper sealing plate. Then, by screwing a nut into the top of the lower rotating shaft, the nut rotates to the top of the limiting post, leaving a certain distance between the nut and the top of the limiting post. Under the action of the nut and the limiting ring, the lower rotating shaft is confined in the upper fixed bushing, allowing it to move back and forth slightly and rotate. Finally, insert the secondary gear into the non-circular shaft.

[0016] By setting up a coupling assembly, power transmission between the main gear and the secondary gear can be realized, and a seal can be effectively formed to prevent soup from flowing out of the round hole.

[0017] A further technical solution is that the filter plate is a circular plate with rectangular grooves extending inward from its edges. The annular side plate is also arranged along the edge of the rectangular grooves to form a cuboid recess. The recess includes two opposing side plates and a connecting plate connecting the two side plates. The recess also contains two mounting pieces. Each mounting piece has a second slot extending away from the grate from the edge of the grate. A first slot is formed at the connection between the side plate and the annular side plate. The recess also contains a roller shaft, which rotates and slides through the first slot and the second slot. In the two slots, the mounting plate is screwed onto the side plate, and two rollers are fixedly sleeved on the roller shaft at intervals. The two rollers are located between the two mounting plates, and the edges of the rollers extend beyond the edges of the mounting plates. The inner wall of the inner tub is a cylindrical inner wall, and a rectangular flat wall is also vertically provided on the inner wall of the inner tub. The left and right sides of the flat wall and the cylindrical inner wall of the inner tub form two vertical angled lines at their connection. The annular side plate does not fit against the inner wall of the inner tub, and the edges of the two rollers are respectively located on the two angled lines, making it impossible for the grate to rotate.

[0018] When using the above solution, the inner wall of the grate and the inner barrel are slidably connected by rollers. By setting two included lines formed by the combination of the flat wall and the cylindrical inner wall, and then using two rollers to roll along the included lines, the rotation of the grate is restricted. The annular side plate is not in contact with the inner wall, which reduces the friction between the grate and the inner barrel and reduces the risk of jamming when the grate is raised or lowered.

[0019] Setting the filter plate to a circular plate can maximize the loading area.

[0020] The design incorporates a first slot, a second slot, and a mounting plate, making the installation of the roller shaft and rollers more convenient, as well as maintenance and replacement.

[0021] A further technical solution is that the base includes a cylindrical base shell, the top of which protrudes upward to form a cylindrical base top shell. The diameter of the base top shell is smaller than the diameter of the base shell. A concave metal heat-conducting cover is detachably mounted on the top of the base top shell. A heating tube is attached to the inner top wall of the heat-conducting cover. The bottom wall of the inner barrel is concave inward to form a cylindrical recess. The top wall of the recess in the bottom wall of the inner barrel is in contact with the top outer wall of the heat-conducting cover. The side wall of the recess in the bottom wall of the inner barrel is in contact with the side wall of the base top shell. The bottom of the inner barrel... The bottom wall outside the recess abuts against the top of the base shell outside the base shell. The upper rotating component is located at the center of the recess. A first through hole is opened at the center of the top of the heat-conducting cover. A second through hole is opened at the center of the top of the base shell. The lower sealing plate of the lower rotating component is installed on the base shell directly below the second through hole. The lower fixed bushing is located inside the second through hole. The upper rotating component passes through the first through hole and is inserted into the lower rotating component. A temperature sensor is also provided on the side wall of the inner barrel. A controller is also provided outside the inner barrel. The temperature sensor and the heating tube are electrically connected to the controller.

[0022] Using the above solution, the cylindrical base shell, heat-conducting cover, and recess allow for quick and easy positioning and insertion of the inner container when installed on the base, effectively preventing shaking. The heating element and heat-conducting cover work together to heat the broth, allowing for on-site cooking. A temperature sensor and controller monitor the temperature of the inner container to control the heating time and power. The visible ingredients and on-site cooking method reassure diners about the broth's quality, promoting the promotion and sale of high-quality broth.

[0023] A further technical solution is that the opening at the top of the inner tub is also provided with an air guide cover. The air guide cover includes a first annular vertical plate. The outer wall of the first annular vertical plate is slidably and sealingly fitted with the inner wall of the inner tub. The top of the first annular vertical plate protrudes outward to form an annular sealing plate. The lower end face of the annular sealing plate is fitted with the opening face at the top of the inner tub. Part of the outer wall of the annular sealing plate protrudes outward to form a receiving plate. An air inlet is also provided between the upper and lower end faces of the receiving plate. A second annular vertical plate is also provided on the upper end face of the annular sealing plate and the receiving plate. The second annular vertical plate encloses both the first annular vertical plate and the air inlet. The soup lid seals the upper opening of the second annular vertical plate. A water receiving tray with an upper opening is also provided at the bottom of the side wall of the base shell. An air guide pipe is also connected to the bottom of the air inlet. The bottom of the air guide pipe is connected to the water receiving tray.

[0024] When using the above method, the steam rising from the broth in the inner pot is continuous. Since the opening of the inner pot is sealed by the soup lid, the steam can only be discharged from the air inlet at the receiving plate and enter the air guide pipe. The steam gradually condenses into liquid in the air guide pipe and is discharged downwards along the air guide pipe into the water receiving tray directly below.

[0025] By using a vent cap and soup lid in conjunction, the moisture in the inner container is sealed off and guided to the air inlet within the sealed space for discharge. A drip tray is installed on the side wall of the base shell to collect the condensed soup. This allows moisture to be discharged without exposure, preventing it from entering the air and affecting customers taking their soup, while also keeping the soup container clean overall.

[0026] A further technical solution is that a water supply pipe is also sealed and inserted through the receiving plate. The top of the water supply pipe is bent and extends to the top opening of the inner barrel, and the bottom of the water supply pipe extends downward to the base. A side wall opening is also provided on the side wall of the base shell. The bottom of the water supply pipe is bent and extends through the side wall opening into the base. An upper liquid level sensor is also provided in the upper part of the inner side wall of the inner barrel, and a lower liquid level sensor is also provided in the lower part of the inner side wall of the inner barrel. A water inlet pipe is also inserted through the side wall of the base shell. The bottom of the water inlet pipe and the water supply pipe are connected through a first pipeline. A first water pump and a first flow meter are also provided on the first pipeline. The upper liquid level sensor, the lower liquid level sensor, the first water pump, and the first flow meter are all electrically connected to the controller.

[0027] When using the above scheme, the inlet pipe is connected to an external water supply source. When the soup in the inner bucket drops to the lower level sensor, the lower level sensor sends a signal to the controller. The controller then starts the first water pump. The first water pump pumps the external water from the inlet pipe into the replenishment pipe, and then discharges it from the top of the replenishment pipe, entering the inner bucket through the opening at the top of the inner bucket. This continues until the soup rises to the upper level sensor, which sends a signal to the controller. The controller then stops the first water pump, and the replenishment pipe stops supplying water. Simultaneously, the first flow meter monitors the replenishment volume. When the replenishment volume reaches a preset threshold or the upper level sensor is triggered, either of these events can trigger the first water pump to stop, providing double protection.

[0028] A further technical solution is that the inner bucket is covered with an outer bucket shell with openings at the top and bottom. The outer bucket shell and the inner bucket together form a soup bucket. A long strip-shaped control panel shell is vertically provided on the outer side wall of the outer bucket shell. The top wall of the control panel shell is flat and has an upper air hole. The bottom wall of the control panel shell is flat and has a lower air hole. The air guide pipe is located in the control panel shell. The upper air hole and the lower air hole are connected by the air guide pipe. The top wall of the control panel shell is attached to the lower end face of the receiving plate, and the upper air hole coincides with the air inlet. A support panel is provided at the upper opening of the water receiving tray. The support panel has an air outlet hole. The air outlet hole is not smaller than the lower air hole. The lower air hole is located directly above the air outlet hole. Several water filter holes are also provided in the support panel. The water supply pipe is located in the control panel shell. The middle and upper ends of the water supply pipe pass through the top wall of the control panel shell. The bottom of the water supply pipe is bent and passes through the side wall of the control panel shell before extending into the side wall opening.

[0029] When using the above solution, an outer shell is installed, with the inner shell placed inside. This serves two purposes: firstly, it provides an aesthetically pleasing exterior; secondly, it isolates the inner shell from diners, preventing burns from the hot inner shell. Furthermore, the water supply pipe and vent pipe are concealed within the control panel housing, avoiding their exposure and improving the overall appearance of the soup pot, while also preventing burns to diners.

[0030] A further technical solution is that the soup dispensing control component includes a second pipeline, a second water pump, and a second flow meter. The water outlet pipe is connected to the water inlet of the soup dispensing pipe through the second pipeline. The second water pump and the second flow meter are located on the second pipeline. The water outlet of the soup dispensing pipe passes through the side wall opening and is installed in the side wall of the control panel housing, extending into the control panel housing. The water outlet of the soup dispensing pipe then passes through the side wall of the control panel housing again from inside the control panel housing and extends out of the control panel housing, and is located above the water receiving tray. The second water pump and the second flow meter are both electrically connected to the controller.

[0031] When using the above solution, concealing the soup dispensing pipe within the control panel housing improves the overall appearance of the soup container and prevents most of the pipe from coming into contact with diners, thus avoiding scalding. Furthermore, by incorporating a second water pump and a second flow meter, when soup needs to be dispensed, the controller activates the second water pump, pumping the soup from the dispensing pipe. The second flow meter calculates the flow rate and controls the pump's operating time, thereby controlling the amount of soup dispensed each time, facilitating restaurant management. By extending the spout of the soup dispensing pipe above the drip tray, diners can place their soup bowls on the tray's support panel to catch any spilled soup.

[0032] A further technical solution is that the control panel housing includes a long strip-shaped front outer shell, the front outer shell having a cavity extending inward from the back, and a removable back panel covering the back of the front outer shell. The front end of the front outer shell has a display screen hole, an operation key hole, and a water outlet key hole from top to bottom. An operation key is slidably installed in the operation key hole, and a water outlet key is slidably installed in the water outlet key hole. A control panel assembly is also installed inside the cavity. The control panel assembly includes the controller, a display screen, and a key circuit board. The display screen is located in the display screen hole. The operation key, water outlet key, and key circuit board are in a press-fit manner. The water outlet end of the soup outlet pipe is located below the water outlet key hole. The key circuit board and the display screen are both electrically connected to the controller.

[0033] When using the above solution, when soup needs to be dispensed, press the operation button. The operation button touches the button circuit board, which transmits a signal to the controller. The controller controls the display screen to show the corresponding soup dispensing prompt, and at the same time controls the second water pump and the second flow meter to make the soup in the soup pot discharged through the soup dispensing pipe.

[0034] By operating the buttons, the heating element and temperature sensor in the soup pot can be controlled to regulate the stewing temperature and time of the soup. The display screen can show this control information, allowing staff and diners to have a clear understanding of the soup's condition and thus increasing their willingness to consume the soup.

[0035] By arranging the display screen, control buttons, water dispensing button, and soup dispensing tube from top to bottom, the top-mounted display screen avoids being obstructed by hands when operating the buttons, providing easily observable prompts. Placing the water dispensing button and soup dispensing tube adjacent to each other increases their interrelationship, allowing diners to quickly locate the water dispensing button and improve their soup-getting experience. Providing the water dispensing button as a separate element also makes it easier for diners to quickly find and accurately press it.

[0036] A further technical solution is that the inner barrel is also provided with an inverted concave filter cover, the top of the filter cover is provided with a circular groove and several filter holes, the filter cover is slidably sleeved on the limiting post through the circular groove, and the bottom of the filter cover abuts against the inner bottom wall of the inner barrel.

[0037] The beneficial effects of this invention are as follows:

[0038] 1. By combining an observation window with a vertically movable grate, diners can see the contents of the inner pot through the broth. The ingredients being cooked in the grate are moved into the observation window via the screw rotation of the connecting parts and the shaft. At the same time, the grate is controlled to keep the ingredients being cooked in the broth at all times, allowing diners to see the ingredients clearly.

[0039] 2. By setting a rotating connector, the inner bucket and the base can achieve quick insertion and connection, while also having the functions of automatically locking the soup when the inner bucket is separated and automatically opening the soup when the inner bucket is inserted. It also takes into account the rotation function. The overall structure is ingeniously designed, small in size, and reliable in use.

[0040] 3. By setting up a heat-conducting cover and heating tube, the on-site cooking function is realized.

[0041] 4. By incorporating a concealed venting design, moisture in the inner container is sealed off and guided to the air inlet within the sealed space for discharge. A drip tray is installed on the side wall of the base shell to collect condensed soup. This allows moisture to be discharged without exposure, preventing it from entering the air and affecting customers taking soup, while also keeping the soup container clean overall.

[0042] 5. By designing concealed water supply and soup dispensing pipes, the exposed water supply and soup dispensing pipes are avoided, improving the overall appearance of the soup pot and preventing diners from being scalded by the water supply and soup dispensing pipes.

[0043] 6. By arranging the display screen, operation buttons, water dispensing button, and soup dispensing tube from top to bottom, the display screen, positioned at the top, avoids being obstructed by hands when operating the buttons and provides easily observable prompts. Placing the water dispensing button and soup dispensing tube adjacent to each other increases their interrelationship, allowing diners to quickly locate the water dispensing button and improve their soup-getting experience. Providing the water dispensing button separately also makes it easier for diners to quickly find and accurately press it. Attached Figure Description
